2958ALUMINUM INDIVIDUALS UNDERGOING HEMODIALYSIS ARE AT RISK FOR ALUMINUM TOXICITY. PROLONGED ACCUMULATION MAY CAUSE ANEMIA, ENCEPHALOPATHY, AND VITAMIN D-RESISTANT OSTEOMALACIA. ALSO, WORKERS EXPOSED TO HIGH LEVELS OR TO LONG-TERM LOW LEVELS OF ALUMINUM DUST ARE AT INCREASED RISK OF TOXICITY.
14451ALUMINUM, 24 HR URINE INDIVIDUALS UNDERGOING HEMODIALYSIS ARE AT RISK FOR ALUMINUM TOXICITY. PROLONGED ACCUMULATION MAY CAUSE ENCEPHALKOPATHY, AND VITAMIN D-RESISTANT OSTEOMALACIA. ALSO WORKERS EXPOSED TO HIGH LEVELS OR TO LONG-TERM LOW LEVELS OF ALUMINUM DUST ARE AT INCREASED RISK OF TOXICITY.
303CALCIUM Calcium is involved in the regulation of neuromuscular and enzyme activity, bone metabolism, and blood coagulation. Calcium blood levels are controlled by a complex interaction of parathyroid hormone, vitamin D, calcitonin, and adrenal corical steroids. Calcium measurements are useful in the diagnosis of parathyroid disease, some bone disorders, and chronic renal disease. A very low level of calcium results in tetany.
91735CARDIO IQ(R) VITAMIN D, 25-HYDROXY, LC/MS/MS MEASUREMENT OF SERUM 25-OH VITAMIN D CONCENTRATIONS PROVIDE A GOOD INDEX OF CIRCULATING VITAMIN D ACTIVITY IN PATIENTS NOT SUFFERING FROM RENAL DISEASE. LOWER THAN NORMAL 25-OH VITAMIN D LEVELS CAN RESULT FROM A DIETARY DEFICIENCY, POOR ABSORPTION OF THE VITAMIN OR IMPAIRED METABOLISM OF THE STEROL IN THE LIVER. A 25-OH VITAMIN D DEFICIENCY CAN LEAD TO BONE DISEASES SUCH AS RICKETS AND OSTEOMALACIA. ABOVE NORMAL LEVELS CAN LEAD TO HYPERCALCEMIA. THIS ASSAY EMPLOYS LIQUID CHROMATOGRAPHY TANDEM MASS SPECTROMETRY TO INDEPENDENTLY MEASURE AND REPORT THE TWO COMMON FORMS OF 25-HYDROXY VITAMIN D: 25OH D3 - THE ENDOGENOUS FORM OF THE VITAMIN AND 25OH D2 - THE ANALOG FORM USED TO TREAT 25OH VITAMIN D3 DEFICIENCY.
90393FAT MALABSORPTION (RESPONSE VIT D2) VITAMIN D (DISTINCT FROM THE VITAMIN D METABOLITES, 25- HYDROXYVITAMIN D OR 1,25 DIHYDROXYVITAMIN D) IS AN ESSENTIAL NUTRIENT OBTAINED VIA EXPOSURE TO SUNLIGHT (CHOLECALCIFEROL) OR DIET (ERGOCALCIFEROL). MEASURING THE VITAMIN D CHOLECALCIFEROL AND ERGOCALCIFEROL CAN BE USED IN THE DIAGNOSIS AND MANAGEMENT OF DISORDERS OF FAT ABSORPTION SUCH AS CROHN'S DISEASE.
718PHOSPHORUS, INORGANIC Serum phosphorus (phosphate) levels alone are limited diagnostic value and should be correlated with serum calcium levels. An increased phosphorus with decreased calcium suggests either hypoparathyroidism or renal disease. A decreased phosphorus and an increased calcium suggests hyperparathyroidsim or sarcoidosis. When both calcium and phosphorus are decreased, diagnostic considerations include malabsorption, vitamin D deficiency, and renal tubular acidosis. Increased phosphorus and normal or increased calcium suggests milkalkali syndrome or hypervitaminosis D.
16761Questassured 25-Hydroxy And 1,25-Dihydroxyvitamin D, Lc/Ms/Ms
91935QUESTASSURED FOR INFANTS, 25-HYDROXYVITAMIN D WHILE MEASUREMENTS OF 25(OH)D PROVIDE A GOOD INDEX OF CIRCULATING VITAMIN D ACTIVITY IN PATIENTS NOT SUFFERING FROM RENAL DISEASE, FOR INFANTS LESS THAN 3 YEARS OF AGE IT IS IMPORTANT TO REMOVE CIRCULATING LEVELS OF THE INACTIVE C3-EPIMER OF VITAMIN D FROM THE SAMPLE SO THAT TOTAL VITAMIN D LEVELS ARE NOT FALSELY ELEVATED. FALSELY ELEVATED RESULTS COULD ERRONEOUSLY MAKE THE CHILD APPEAR TO BE WITHIN NORMAL LIMITS AND RESULT IN POTENTIAL UNDER-TREATMENT. LEVELS OF C3-EPIMER IN OLDER CHILDREN AND ADULTS ARE USUALLY NEGLIGIBLE AND DO NOT CAUSE FALSELY ELEVATED VITAMIN D RESULTS. THIS ASSAY EMPLOYS ADVANCED LIQUID CHROMATOGRAPHY - TANDEM MASS SPECTROMETRY, WHICH ENABLES THE CHROMATOGRAPHIC SEPARATION OF THE C3-EPIMER FROM 25-OH VITAMIN D THEREBY ALLOWING ACCURATE MEASUREMENT IN THE PRESENCE OF C3-EPIMER. WHILE THIS ASSAY WILL PRODUCE ACCURATE VITAMIN D RESULTS ON PATIENTS OF ANY AGE, IT IS SPECIFICALLY INDICATED FOR INFANTS LESS THAN 3 YEARS OF AGE.
16558VITAMIN D, 1,25 DIHYDROXY LC/MS/MS THIS TEST MEASURES THE BIOACTIVE FORM OF VITAMIN D. IT IS USED IN THE DIFFERENTIAL DIAGNOSIS OF HYPOCALCEMIA AND TO MONITOR PATIENTS WITH RENAL OSTEODYSTROPHY OR CHRONIC RENAL FAILURE. THIS TEST IS NOT SUITABLE FOR DIAGNOSIS OF VITAMIN D DEFICIENCY AND MONITORING SUPPLEMENTATION IN MOST PATIENTS. THE 25 HYDROXYVITAMIN D TEST IS THE RECOMMENDED TEST FOR THOSE PURPOSES (N ENGL J MED. 2007;357:266-281).
51449Vitamin D, 25 Hydroxy And 1,25 Dihydroxy, Lc/Ms/Ms This test measures the bioactive form of Vitamin D. It is used in the differential diagnosis of hypocalcemia and to monitor patients with renal osteodystrophy or chronic renal failure. This test is not suitable for diagnosis of Vitamin D deficiency and monitoring supplementation in most patients. The 25 hydroxyvitamin D test is the recommended test for these purposes. (N. Eng J Med. 2007:357: 266-281.)
